Hello,
I have not been successful getting the TMS320F28335 XINTF to write to a flash chip. The Chip select and address lines seem to be working. However, I noticed the Write Strobe is not going low when I execute the following 3 lines of code.
*((Uint16*)0x200555UL)= 0x00AAU;
*((Uint16*)0x2002AAUL)= 0x0055U; *((Uint16*)0x200555UL)= 0x0020U;
.
Those three lines are in the flash drivers initialization function. They occur after the external interface is initialized.
After stepping over those three lines of code, I run to a function that contains the following code. When I try to step over *((Uint16*)0x200555UL) = 0x00A0U; in the code shown below, CCS pops up with a error dialog box and the error shown below in the command window.
What could be causing the CCS error?
